“Most climate scientists
believe that there is evidence that explains global warming” is best supported by
this study.
The drastic increase in the emission of CO2 (carbon dioxide)
within the last 30 yearscaused<span> by burning fossil fuels has been identified as
the major </span>reason<span> for
the change of temperature in the atmosphere (click the following link for a
summary and graphs about the </span>cause<span> and

The correct answer between all
the choices given is the last choice or letter D. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and

(30, 5)
(10, 1)
change of y / change of x
= (30 - 10) / (5 - 1)
= 20 /4
= 5
Answer:
915 Hz
Explanation:
The observed frequency from a sound source is given as
f₀ = f [(v + v₀)/(v+vₛ)]
where
f₀ = observed frequency of the sound by the observer = ?
f = actual frequency of the sound wave = 983 Hz
v = actual velocity of the sound waves = 343 m/s
vₛ = velocity of the source of the sound waves = 55.9 m/s
v₀ = velocity of the observer = 28.4 m/s
f₀ = 983 [(343+28.4)/(343+55.9)]
f₀ = 915.2 Hz = 915 Hz
